Since January 2009, a lot of people have upgraded to smartphones with powerful built-in cameras. Four years ago, smartphones only accounted for 11% of global smartphone sales, according to Gartner. In the third quarter of 2012, the smartphone accounted for 39.6% of phone sales around the world.

All those more powerful phones mean the chance to share juicier content with friends who didn't make it to the inauguration. According to Verizon Wireless, data usage in D.C. has increased 12-fold since the last inauguration in 2009.

So to meet the increased demand, the major carriers are spending a lot of money to beef up their networks in the nation's capital.

We just saw Michelle Obama and...it appears she has changed. For those looking at the fashion today, it looks like you'll have to search for what outfit #2 is. Look back at Inaugural fashion.

A sea of American flags engulfs on the National Mall. CNN's Kevin Liptak reports virtually everyone on the Malll now has an American flag to wave -- they were handed out by volunteers who said they were Obama supporters. (Photo: Mario Tama/Getty Images)
